Freezing Point Depression Formula: Constant, Mollar Mass

To understand the Freezing Point Depression Formula , lets first learn about freezing. The phase transition of a material from a liquid state to a solid state is referred to as freezing. The phenomenon is known as a phase transition, which occurs when a material changes from one state of matter to another. The solid and liquid states coexist at the freezing point because these two phases, liquid and solid, are in balance.

Chemistry Formula For Depression In Freezing Point

Causes of Depression in Freezing Point

• There is an equilibrium between a solvent's liquid and solid states at its freezing point.
• This suggests that the liquid and solid phases have the same vapour pressures.
• The vapour pressure of the solution is discovered to be lower than the vapour pressure of the pure solvent upon the addition of a non-volatile solute.
• As a result, the solid and the solution come into equilibrium at lower temperatures.

Factors Affecting the Freezing Point

• A material's high freezing point indicates strong intermolecular forces between its molecules.
• The freezing point is quite low if the forces are weak.
• When the solid and liquid phases are in balance, a liquid freezes or a solid melts.

Examples of Chemistry Formula For Depression in Freezing Point

• Seawater has a lower freezing point than 0 degrees Celsius. At temperatures below the freezing point of pure water, seawater is still a liquid. This is a result of the dissolved salts in the saltwater.
• A solution of ethanol in water is another typical example of this phenomenon. The mixture has a freezing point that is greater than pure ethanol but lower than pure water.
